Convert X Window Dump (.xwd) to APNG for free. Choose files, review the available settings and download your results. No account needed.
An image dump format produced by the X Window System’s xwd utility. It stores captured pixels with information describing the display format.
The file is decoded locally as an image; no connection to an X server is needed.
XWD file format guideAn extension of PNG for multiple animation frames with full-color images and alpha transparency. APNG can avoid GIF’s limited color palette.
Treat animated input separately from canvas still images. A still-image output intentionally keeps one frame.
APNG file format guideChoose dimensions and image quality before converting. Still-image exports keep one frame. Unedited GIF, WebP, AVIF, JPEG XL and MNG conversions can retain animation. Animated edits use a GIF intermediate with a limited color palette. Canvas editing uses browser display precision and does not preserve original EXIF, HDR, or scientific image data.
